STOVE-DOOR FITTING.

Specification of Letters Patent.

Application filed'February 24, 1920. Serial No. 361,037.

To all whom it may concern: I

Be it known that I, THOMAS J. MCWIL- LIAMS, a citizen of the UnitedStates, residing at 1519 Clark avenue, in the cit of Cleveland, countyof-Cuyahoga, and tate of Ohio, have invented a new and usefulImprovement in Stove-Door Fittings, of which the following is aspecification, the principle of the invention being herein explained andthe best mode in which I have contemplated applying that principle, soas to distinguish itfrom other inventions.

My invention pertains to a stove door fitting and more particularly tothe manner of connecting a stove door about its hinge.

The objects of my invention, besides designing a construction of thischaracter which will be of simple, durable and sightly construction, are

1. To conceal a lug required to support a downwardly swinging door whenit is in its lowermost or substantially horizontal position. Instead ofhaving such lug, which is commonly used for this purpose, positioned infront and externally, I reverse the construction by providing the luginternally and behind the plane of the door opening. Instead of the doorswinging down to rest upon'the lug or lugs a projection from the bottomof the door swings upwardly against the underside of a lug or lugs. v

2. To provide flush bordering surfaces for the sill of a peculiar doorin. a door construction shown described and claimed in the co-pending H.J. Trenkamp application for Stove oven entry filed May 9, 1919, SerialNo. 295,885. According to the disclosure of such prior application alarge door was hung to swing downwardly and such large door carried twocomplementary doors hinged to swing in opposite directions sidewise. Mypresent invention enables dishes to he slid out of the oven compartmentwithout encountering a ridge where the edge of the doorconforms to theedge of the oven compartment; and this facility obtains regardless ofwhich door is open.

Adverting to the drawings Figure I is a front elevation of a stoveembodying my invention, showing all doors closed.

Fig. II is a horizontal section on line II--II of Fig. I lookingdownwardly. Fig. III is a. vertical section on line III--III of Fig. I.looking to the left, and with the main door open. i

Fig. IV is an enlarged vertical section on line IV--IV of Fig. I lookingtoward a hinge showing the relation of the parts when the door isclosed.

Fig. V is a section corresponding to that of Fig. IV showing therelation of the parts when the door is opened.

Fig. VI is an enlarged fragmentary front elevation with certain portionsindicated in dotted lines. a

Fig. VII is a section on line VII-VII of Fig. VI.

Fig. VIII is a similarly enlarged horizontal section on line VIII-VIIIof Fig. I.

The stove casing is supported on four legs 1 and comprises a bottom 2, afront frame 3, side walls 4, a rear. wall 5 having an open Patented,Oct. 25, 1921.

ing above in communication with a stack 6 and a top 7. Supported in anysuitable manner within the stove casing so as to be spaced from the sidewalls 4 and the rear wall 5 is an oven compartment comprising a bottom8, rear wall 9 and side walls 10. Inasmuch as the manner of sosupporting an oven is old in the art and forms no part of this inventionits detailed description has been dispensed with. In consequencehowever, of such spaced relation of the oven compartment, an envelopingflue space 11 is provided. Carried by the inner surface of the rear wall5 are brackets 12 supporting each one end of burners 13 which have theiropposite ends 14 supported in the front wall 3. The manner of ignitingthe burners 13 is of no interest to this application. Sufiice it to saythat each burner 13 is located underneath the middle of one lateral halfof the oven compartment. The burners 13 are both supplied with fuel froma gas sup ly pipe 15, from which the flow is control ed by valves 16.

It is to be understood that the entire space available within the stovefor the purposes of an oven is open at the front side but may be dividedin half by means of a removable artition 17 shown in Figs. II and III.large 'door will afford access to the entire oven space while twosmaller doors will afford access to the divisions of the oven onopposite sides-of the partition 17 when the latter is in place.

As will be observed in Fig. VIII the edge 18 nions 21, being thusadapted to swing downw-ardly toward a horizontal position. Means isprovided for limiting such downward swinging movement and thearrangement is additionally such that when the horizontal position isreached no part; of the door will project higher than the level of thebottom 8. Secured to the trunnions 21 are a pair of levers 22 andconnected with the free ends of the latter are a pair of tension springs23. The opposite ends of these springs are attached to the frame of thestove in a manto resist the downward swing of the door 19 and-to easeits return or closing action. The

two extreme positions of the lever 22 and spring 23are shown in Figs. Vand VII respectively. The front frame of the stove is provided onopposite sides with a pair of forwardly curved caps 24 adapted toinclose the trunnions 21 and conceal the levers 22. Depending from thetwo lower corners of the door 19 are a pair of lugs 25 adapted to swingupwardly to the rear in suitable recesses 26 as shown in Figs. I- and IVto VII inclusive, so as eventually [to engage abutments or stop surfaces27 as shown in Fig. V. When such engagement occurs the main door 19 willbe in a substantially horizontal position, according to one feature ofmy invention. The inside surface 28 of that portion of the door framewhich extends between the trunnions 21 will be precisely level with theupper surface of the bottom 8 of the oven compartment as appears in Fig.III and still more clearly in Fig. V.

- This makes it very much easier to withdraw any baking receptacle andenables the same .to he slid smoothly owing to the absence of anyobstructing edges.

As may be seen in Fig. VIII the innermost upright edge 29 of the maindoor frame 19 is adapted to abut the recessed edge 18 when the main dooris closed thereby afi'ordingan effectual heat seal. 1

Hinged at 30 and 31 on two opposite sides of the main door are a pair ofsmaller doors 32 and 33 provided with handles 34 and 25- respectively.,These doors are adapted to swing laterally in opposite directions whenthe main door is closed. Inspection again of Fig. VIII discloses thatwhen the door 32 is closed against. the frame 19, it effects engagementtherewith along an upwardly extending plane 36 thereby similarly forminga heat seal. I

For the same reason that the surface 28 is level with the bottom 8 whenthe main door is open, I. have so designed the conshown in Fig. V.

Clearl it is of equal advantage to be able to withd i'aw a baking dishwithout having its bottom encounter an obstruction when either of thesmaller'doors 32 or 33 are open. I have, therefore, as appears in Fig.IV, also so fitted the parts that the upper "edge 38 the lowerhorizontal front line of the oven compartment will, when the main dooris closed rest level with the bottom 8. In this manner, when either ofthe smaller doors is open,'a baking receptacle may be withdrawn smoothlyor momentarily allowed to rest in a level position partly upon thebottom 8 and partly upon such bordering edge 38 preparatory to beingregripped and either returned for further baking or lifted out of theoven. Since the upper edge 38 moves only when the large door opens,manifestly, it occupies the same position as shown in Fig. IV when thesmaller door 32 is open. Therefore, if the door 32 is considered 'ashaving been swung 0 en and out of the way, it is clear that ha ingutensils may be smoothly slid from the bottom 8 over the surface 38which remains level therewith.

1. A stove' door fitting comprising the combination with a stove havingan oven compartment, of a door adapted to afford access to one entireside of said comparts ment and to have its inside wall rest level withthe bottom of said compartment, another door carried by said firstmentioned door and adapted to afford direct access to only a part ofsaid compartment, a stationary part of said larger door resting levelwith the bottom of said oven compartment to form a continuous smoothsurface when said smaller door is opened.

2. A stove door fittingcomprising the combination with a stove having anoven compartment, provided with a sill, of a horizontally hinged dooradapted to afi'ordaccess to one entire side of said compartment and tohave its inside wall rest level with said sill, another door verticallyhinged to of the main door frame 19 which borders 2 comprising a supportprovided with a substantially horizontal surface, and a member movablyattached to said support, said member being fashioned with two surfacesangularly disposed with reference to each other, each of said membersurfaces being adapted to assume a position level with said supportsurface depending upon the position of said member relative to saidsupport.

5. A stove door fitting comprising the combination with a stove havingan oven compartment including a bottom, of a door for said oven andmovably carried by said stove, said door being adapted to assume twodifferent positions of rest and fashioned with surfaces adjacent to adefining edge of said oven compartment and adapted each to come levelwithsaid bottom when said door is in one of its positions of rest.

6. A stove door fitting comprising the combination with a stove havingan oven compartment including a bottom, of a main door for said oven andhinged to said stove, a smaller door hinged to said main door, thelatter being fashioned with edges bordering an edge of said ovencompartment and each adapted to assume a position substantially levelwith said oven bottom when the main door is open and closedrespectively, whereby baking utensils may be smoothly slid from saidoven regardless of which door is opened.

7. A stove door fitting comprising the combination with an oven bottom,of a door provided with distinct edges adapted to lie level with saidbottom when said door is open and closed respectively.

8. A stove door fitting comprising the of doors to said oven carried oneby the other, said carrying door provided with distinct edge surfacesdisposed in angularly related planes, one of said edges being level withsaid oven bottom when such carrying door is open, and the other edgesurface being level with saidoven bottom when such carrying door isclosed for the purpose specified.

9. A stove door fitting comprising in combination, a compartmentprovided with an abutment, a spring attached to said compartment and adoor provided with two lugs, one lug adapted to engage said abutment andthe other lug to be restrained bysaid spring respectively.
